The 2D to 3D conversion technique plays an important role in the development and promotion of three-dimensional television (3DTV), because it can provide adequate supply of high-quality 3D program content. This Paper focuses on the real-time implementation of 2D-3D system, of which the major parts are source depth-map generation and depth image-based rendering (DIBR). The depth-map is generated by...
In this paper, an efficient depth image based view rendering method for high quality multiview virtual images synthesis is proposed, which utilizes two color images with their associated depth maps. The proposed method consists of four main steps. The first step is virtual camera parameters design by using shift-sensor camera model to avoid the keystone distortion. Secondly, the mixed color pixels...
With the development of display hardware, computing power, transmission and rendering algorithm, 3DTV is becoming the most promising technology that provides the users a more natural viewing experience than 2D displays. But most 3D movies need to wear 3D glasses to watch. Naked eye 3D is the ultimate goal of the development of 3D technology. Multi-view rendering by depth image based rendering (DIBR)...
Recent computer vision technology has made great progress in 3DTV industry. The advent of 3DTV to the home raises a number of challenges beyond the basic display of an available stereo pair. One of them is the production of 3D augmented contents. To present virtual objects over the real world, the existing method is offline processing in postproduction. It is a difficult and expensive work since flexible...
This paper focuses on the near real-time implementation of end-to-end 3DTV System. It is specially designed for the generation of high-quality disparity map and depth-image-based rendering (DIBR) on the graphics processing unit (GPU) through CUDA (Compute Unified Device Architecture) API. We propose our novel methods including a kind of stereo matching with adaptive windows and an asymmetric edge...
An asymmetric edge adaptive filter (AEAF) is proposed in this paper to partially solve two puzzles in 3DTV, i.e. depth generation and hole filling. Different from other similar processing methods, one time of AEAF operation can simultaneously achieve the effect of edge correction and pre-processing of the depth maps. Thus the computing complexity can be greatly reduced. On the one hand, based on the...
